free radical free radical. (chemistry). An atom or a diatomic or polyatomic molecule which possesses one unpaired electron. Also known as a radical.ree radical. in chemistry, a molecule or atom that contains an unpaired electron but is neither positively nor negatively charged. Free radicals are usually highly reactive and unstable.

What are radicals in math? Best Answer: The word radical means root. (Look up radical in a dictionary.) Square roots. cube roots, any root expressed with the √ symbol. A fraction is not a radical, but a fraction may contain a radical.adical the root of a quantity as indicated by a square root on a calculator (aka) the radical sign.a number(the index) placed to the left of the sign e.g third root. fourth root. if there is no number the root is a square root.

- An electrochemical cell in which the chemistry is spontaneous is called a voltaic cell. This means that the oxidation will occur spontaneously at the anode and the reduction spontaneously at the cathode. We should note that the notation of something as a voltaic cell is a choice.

Chemical reaction Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur. The substance (or substances) initially involved in a chemical reaction are called reactants or reagents.

Radical Written By: Radical, also called Free Radical, in chemistry, molecule that contains at least one unpaired electron. Most molecules contain even numbers of electrons, and the covalent chemical bonds holding the atoms together within a molecule normally consist of pairs of electrons jointly shared by the atoms linked by the bond.

Definitions &Translations Thus in the electrolysis of water oxygen is the anion and hydrogen is termed the kation. In this case both anion and kation are elements. In the decomposition of copper sulphate the anion is properly speaking sulphion (S O4), a radical, and the kation is copper, an element.

- Radical (chemistry) In chemistry, a radical (more precisely, a free radical) is an atom, molecule, or ion that has an unpaired valence electron. With some exceptions, these unpaired electrons make free radicals highly chemically reactive towards other substances, or even towards themselves: their molecules will often spontaneously dimerize or polymerize if they come in contact with each other.

What are Free Radicals? Free radicals, also known simply as radicals, are organic molecules responsible for aging, tissue damage, and possibly some diseases. These molecules are very unstable, therefore they look to bond with other molecules, destroying their health and further continuing the damaging process.

Unit 5: Radicals and Radical Reactions Bond homolysis forms not one but a pair of radicals. When this radical pair is formed by solution homolysis, it is often considered to be a caged radical pair. That is, the initially formed radical pair is surrounded by solvent molecules, bu no solvent molecules intervene between the pair.

Radical (chemistry) In chemistry, a radical (more precisely, a free radical) is an atom, molecule, or ion that has unpaired valency electrons.ost radicals are reasonably stable only at very low concentrations in inert media or in a vacuum. A notable example of a free radical is the hydroxyl radical (HO•), a molecule that has one unpaired electron on the oxygen atom.

What does it mean to be radical in politics? Radical can mean a number of things ranging from a particularly out-spoken brand of politician, to a fire-brand, to a revolutionary (literally).

antioxidant A free radical is any atom or molecule that has 1 or more unpaired electrons and is therefore highly reactive, seeking to acquire electrons from other substances. Free radicals are normally scavenged from tissues by the antioxidant enzymes superoxide dismutase and glutathione peroxidase.
